By the early 1820s, many Latin American countries had won their independence from Spain or Portugal, with the U.S. government recognizing the new republics of Argentina, Chile, Peru, Colombia, and Mexico in 1822.

Russia had also inspired concerns of imperialism, with Czar Alexander I claiming sovereignty over the territory in the Pacific Northwest and banning foreign ships from approaching that coast in 1821
